The TAS6584-Q1 is a four-channel, digital-input, high-voltage, Class-D audio amplifier that supports up to 45-V supply voltage. In combination with up to 10-A output current, this device delivers maximum output power and high fidelity audio in high and low impedance loads. The device provides four channels at 118 W (45 V, 8 Ω, 1% THD, BTL) and 215 W (45 V, 4 Ω, 1% THD, BTL).

The TAS6584-Q1 integrates DC and AC load diagnostics to determine the status of the connected loads before enabling the output stage. During audio playback, the status can be monitored through output current sense which is available for each channel and reports the measurement to a host processor through TDM with minimal delay. The device monitors the output load condition while playing audio using real-time load diagnostics which operate independent from host and audio input.

To optimize system efficiency, the integrated DSP of the TAS6584-Q1 enables Class-H envelope tracking control, eliminating the need for development of complex tracking software and making local boost voltage control possible without the need for an external microcontroller.

The TAS6584-Q1 device features an additional low-latency signal path for each channel, providing up to 70% faster signal processing at 48 kHz which enables time-sensitive Active Noise Cancellation (ANC), Road Noise Cancellation (RNC) applications.

The device is offered in a 64-pin QFP package with the exposed thermal pad up.
